' HOUSE VENTILATION. l

SPECIFICATION forming part of Letters PatentlNo. 521,038, dated une 5, 1894.

Application ned lingua 14,1893.

To all whom t may concern:

Be it known that I, JosnPH MCCREERY, a citizen of the United States, residing at De? troit, county of Wayne, State of Michigan, .have invented a certain new and useful Improvement in House Ventilation; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements in a system and means of Ventilation and purification of the atmosphere in buildings of various kinds, the same being hereinafter specified and claimed and illustrated in the accompanying drawings, in which-` Figure 1 is a vertical section, showing parts in elevation illustrating features of my invention, with an air flue and branch pipe communicating therewith. Fig. 2 is a vertical section showing also a purifying tank inter# posed in the induction pipe.

Turning now to the drawings A represents any building, shown in this instancewith an underground apartment A in which is located a fan B of any suitable construction. For the introduction of currents of air into the building, the fan is a fan blower. To force air from any apartment, the fan would be a suction fan.

C is'any desired power or motor to operate the fan, as anelectric motor, a steam engine or any motive'power may, however, be employed.

D is a pipe leading to the outer atmosphere. As shown in the drawings, this pipe is carried above the top of the building. For the introduction of fresh air the pipe may be carried to any desired height, so as to reach a pure atmosphere, free fromcinders and other impurities, as far as practicable.

In order to deaden the sound of the fan, and motor and prevent the sound thereof from being carried by the pipes throughout the building, my invention contemplates the introduction into the main air pipe E, of a joint Gr, to prevent'the communication of the noise therethrough. It is well understood that metallic pipes are adapted to convey Serial No, 483,146. (No model.)

sound. I therefore introduce the joint G to overcome this sound conveying tendency. This joint G may be formed ofany suitable material to accomplish the desired end, thus for example, it might be made of felt,.rubber, 0r analogous material, and when so made and introduced into the pipe E, it will have the sure elfect of preventing the passage of any vnoisefrom the motor or fan therethrough.

This sound deadener being a joint in the pipe prevents any vibrations of the pipe from being conveyed beyond such joint.

' In Fig. 2, is shown an air cleaning device of which Q represents a tank, which may be provided with a series of depending wings Q',

and a series of upwardly projecting wings Q2,

separated one from another to-divert the current of air passed therethrough. Any desired fluid Vmay be located in the bas'e of the tank Q, the two sets of Wings forcing thek current of air to commingle with the fluid to wash the air or separate therefrom its impurities. These wings may be covered with asbestus or other suitable material to catch and extract the smoke from the air forced through said tank. Each wing, it will be seen, affords a free passage of air over its extremity, as shown. This tank Q may be located in any desired position.

R denotes any ordinary air flue into which a branch pipe F communicates toward the upper end of the liuc to admit air thereinto under pressure to cause a circulation 'of air through the air iiue. By admitting the air passed through the branch pipe F into the upper end of the air liuc, a circulation is readily effected, without theadmitted current having to lift a volume of air above it, in the liue, as would be the case did the branch pipe F communicate with the base of the air flue. Also if air were forced up the flue, R, it would not so effectively remove the air from the apartments, because the air passing up the ue having to overcome the weight of air in the iiue would not pull the air out of the apartments through the inlets into the flue as well as is done by the air passing into the top of the flue.

I am made aware that itis not new in a ventilating apparatus to have in a pipe a sound deadener which deadens the noise of the air passing through such pipe. But in my device IOO my sound deadener is to prevent the vibrations of the pipe being conveyed `beyond such deadener, and this deadener is made in the form of a joint in such pipe.

I am also made aware of United States Patent No. 268,674, wherein is shown asteam mutfier consisting of a `piece of rubber tubing placed in a steam pipe to deaden the sound terial interposed therein, such joint being ea- ;Dable of `longitudinal denture, `as set forth.

2. In combination, arotatable fan, eduction and induction pipes communicating therewith, one of said pipes provided with a joint of felt substantially as and for the purpose described.

3. In combination, a rotatable fan,induction and eduction pipes communicating therewith, andan air flue having several inlets, said ed uction pipe communicating with said air nue above the topmost inlet of said flue, substantially as and for the purpose specified.

In testimony whereof I sign this specification in the presence of two witnesses.

JOSEPH MCCREE'RY.
